By paster film folded antenna attached to cell phone rear cover outer surface and battery of mobile phone inner surface, transmit the faint radiofrequency signal of plug-in type smart card meter surface antenna emission, make the plug-in type smart card realize that successfully the detailed process of non-contact function is as follows:
When mobile phone was in open state, the contact interface of plug-in type smart card provided the required power supply signals of contact interface work such as VCC, CLK, I/O by the draw-in groove in the mobile phone by mobile phone for it; And, provide work required power supply signal by mobile phone VCC for it, and provide signals such as the required clock of work, data for it by radio-frequency antenna attached to plug-in type smart card surface for the noncontact interface of plug-in type smart card.At this moment, the communication pattern between the plug-in type smart card of mobile phone inside and the card reader of outer handset is an active mode, that is, the signal energy of plug-in type smart card is directly provided by battery of mobile phone, rather than is provided by the card reader of outer handset.Under this communication pattern, when the plug-in type smart card of mobile phone inside enters the working range of outer handset card reader, the antenna of card reader is launched signals such as clock, data, this signal change attached to the magnetic flux of the paster film folded antenna coil on the cell phone rear cover outer surface, thereby in this aerial coil, produce induced current, induced current is in the internal flow of paster film folded antenna, as shown in Figure 5.When in the paster film folded antenna coil of induced current flow on sticking to the battery of mobile phone inner surface, this lip-deep paster film folded antenna coil produces a new electromagnetic field, similarly, this electromagnetic field has changed the magnetic flux attached to the aerial coil on the plug-in type smart card surface, make to produce an induced current in the aerial coil on plug-in type smart card surface, and enter the plug-in type intelligent card chip through plug-in type smartcard internal circuit and carry out signal processing.Signal after the plug-in type intelligent card chip is handled, VCC provides power supply signal by mobile phone, and launch by plug-in type smart card meter surface antenna, the same then magnetic flux that changes attached to the paster film folded antenna coil on the battery of mobile phone inner surface, thereby produce new induced current therein, this new induced current is in the internal flow of paster film folded antenna, as shown in Figure 5.When in the paster film folded antenna coil of induced current flow on sticking to the cell phone rear cover outer surface, this lip-deep paster film folded antenna coil will produce a new electromagnetic field, this electromagnetic field has changed the magnetic flux of card reader antenna equally, thereby produce an induced current thereon, this induced current enters card reader chip through the card reader internal circuit and carries out signal processing.During Here it is mobile phone power-on, the plug-in type smart card is realized in the non-contact function process, the whole process that signal of communication transmits mutually between the plug-in type smart card on card reader and the mobile phone.
When mobile phone is in off-mode, the contact interface of plug-in type smart card will quit work; And, provide signals such as the required power supply signal of work, clock and data for it by radio-frequency antenna attached to plug-in type smart card surface for the noncontact interface of plug-in type smart card.At this moment, communication pattern between the plug-in type smart card of mobile phone inside and the card reader of outer handset is a passive mode, that is, the signal energy of plug-in type smart card is not to be provided by battery of mobile phone, but is provided by the card reader of the outer handset mode by coupled electromagnetic field.Under this communication pattern, when the plug-in type smart card of mobile phone inside enters the working range of outer handset card reader, the antenna of card reader is launched signals such as clock, data, this signal change attached to the magnetic flux of the paster film folded antenna coil on the cell phone rear cover outer surface, thereby in this aerial coil, produce induced current, induced current is in the internal flow of paster film folded antenna, as shown in Figure 5.When in the paster film folded antenna coil of induced current flow on sticking to the battery of mobile phone inner surface, this lip-deep paster film folded antenna coil produces a new electromagnetic field, similarly, this electromagnetic field has changed the magnetic flux attached to the aerial coil on the plug-in type smart card surface, thereby produce an induced current in the aerial coil on plug-in type smart card surface, and enter the plug-in type intelligent card chip through plug-in type smartcard internal circuit and carry out signal processing.A faradic part that produces in the aerial coil on this plug-in type smart card surface is used to support the plug-in type intelligent card chip, handles for it provides signals such as clock to receiving from card reader of enough energy, data; This faradic another part is used for the plug-in type intelligent card chip and attached to the antenna on plug-in type smart card surface, launches the radiofrequency signal of handling through the plug-in type intelligent card chip for they provide enough energy.Signal after the plug-in type intelligent card chip is handled, provide power supply signal by a faradic part that produces in the aerial coil on the plug-in type smart card surface, and launch by plug-in type smart card meter surface antenna, the same then magnetic flux that changes attached to the paster film folded antenna coil on the battery of mobile phone inner surface, thereby produce new induced current therein, this new induced current is in the internal flow of paster film folded antenna, as shown in Figure 5.When in the paster film folded antenna coil of induced current flow on sticking to the cell phone rear cover outer surface, this lip-deep paster film folded antenna coil will produce a new electromagnetic field, this electromagnetic field has similarly changed the magnetic flux of card reader antenna, thereby produce an induced current thereon, this induced current enters card reader chip through the card reader internal circuit and carries out signal processing.During Here it is mobile phone shutdown, the plug-in type smart card is realized in the non-contact function process, the whole process that signal of communication transmits mutually between the plug-in type smart card on card reader and the mobile phone.
The magnetic field intensity that forms attached to the paster film folded antenna on cell phone rear cover outer surface and the battery of mobile phone inner surface is tested, the analytical test result obtains the magnetic field distribution situation: maximum near the aerial coil central point, along with the increase gradually of the distance of central point, magnetic field intensity reduces gradually.Obviously, very desirable attached near magnetic field intensity two end faces of the paster film folded antenna on cell phone rear cover outer surface and the battery of mobile phone inner surface, and induced current loses the signal of communication energy hardly when paster film folded antenna coil inside flows.In addition, the magnetic field distribution situation in the magnetic field that forms in conjunction with the plug-in type smart card meter surface antenna that before obtained, the preferred structure of the described antenna sets of this utility model is, plug-in type smart card meter surface antenna hub of a spool point overlaps with central point attached to the paster film folded antenna coil on the battery of mobile phone inner surface.Therefore, can realize the transmission of signal of communication energy well attached to the paster film folded antenna on cell phone rear cover outer surface and the battery of mobile phone inner surface, that is to say by this paster film folded antenna, the faint radiofrequency signal that the plug-in type smart card meter surface antenna of mobile phone is launched can make the plug-in type smart card can successfully realize non-contact function from the mobile phone internal delivery to the mobile phone outside.
On the one hand, because the work of plug-in type smart card the time places in the draw-in groove, this requires gross thickness that plug-in type card and the antenna that adheres to be superimposed less than 1mm.On the other hand, because cell phone rear cover need play the effect of tight capping battery of mobile phone and internal structure thereof, this requires to be less than 0.1mm attached to the thickness of the coupling part between two surfaces of paster film folded antenna of cell phone rear cover outer surface and battery of mobile phone inner surface, and each surperficial thickness is less than 0.2mm.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
